I was explaining to someone why I LOVE this site! It's the only site where you post your weight with your GAINS and losses for everyone to see comfortably!
-- It's the not the fall! It's how fast you get back up!
It will take 3-4 days for your body to recover and get back to your low. Focus on your diet/exercise the next week. Weigh in knowing you are in recovery for a few days and you'll get through it!
